The guys over at d-addicts were nice enough to inform me about this stuff:

On behalf of D-Fansubs (the people that created hardsubs for your Jumong episodes), we request that you remove our videos from your site. YA Entertainment's lawyer contacted D-Addicts.com and told us to remove any videos that they have licensed in North America from our site. This includes both hardsubbed and raw video files. Here is a list of dramas that they included...they are all Korean (except, strangely, Meteor Rain):

Jeez I'll end up having to buy all the shows I want to watch if they get licensed...I mean I LOVE LOVE LOVE that Korean dramas are getting licensed and released in the US...but I really can't afford it .....

but The Secret Lovers is not in the list...man this really sucks...since i haven't gotten to watch any dramas here. i guess i should watch them and make use of my supporrting before they all get licensed ^^
